Michelin is continuing its relationship with the world-famous national park through the Yellowstone Park Foundation. To date, Michelin has donated more than 1400 tires to equip the park's fleet of 800 vehicles, including patrol cars, garbage trucks, earthmoving equipment, snow plows, and tractor-trailers.

Michelin field engineers have shared their expertise with the park's fleet maintenance managers and staff, and reduced the park's consumption of raw materials by changing the practice of replacing tires annually, to running tires an average of 2 to 3 years. Additionally, feedback from real-world use in the park resulted in the design of a new tire tread engineered to operate in snow, mud, ice, and pavement, rather than necessitating a separate snow tire.

Donations of Michelin tires, as well as improved fuel economy from the optimized tires, have resulted in savings of more than $250,000 per year for the park, or approximately 12 percent of the park's fleet and road maintenance budget.
